Deadlock In Java Multithreading
Aug 24, 2014This is my own coding for understanding deadlock in multithreading . But my doubt is whether this program mirrors the concept of deadlock perfectly or not. If not what should i do to make this code a perfect deadlock.

class A

B bc;

Traffic Light Simulation Using Multithreading
Feb 2, 2015I am writing a simple program to simulate a traffic light. What I want is to make them glow after each 1 second, one by one. For example: Firstly Red, then after 10 seconds, red will be put to off and yellow will start glowing and then accordingly green. This process shall continue incessantly (Just for experimental purpose). I have some arrangement done but could not figure out how to put them together in run() method of Runnable interface. I know how interthread communication works. But could not find any logic in this case when three threads will run together.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TrafficLight extends JFrame implements Runnable
{
JButton red, green, yellow ;
TrafficLight()

If the user pressed a button that had started a thread (in the main screen, MainController.java), I need to recover it to display the information that contains to display it on the controls of Details Screen ( a second screen, DetailController.java).
What Class do you recommend for this? Service?

View Replies View RelatedRead Three Files Using MultiThreading And Write Into A New File
Apr 21, 2014I got a question in my last interview, its all about multithreading, interviewer asked me to write a program, to write the contents of three files(F1,F2,F3) in to a new File F4, using multithreading , first thread should read the first file and second thread should read second file, so the File F4 should contain F1's contents in first then F2's contents after that etc. I tried to give my best shot, but i couldn't get a way to ensure that the first thread is reading the first file and write to F4 then second thread reading the second file and writing once first file is written completely into F4 and so on ..how to do this?

View Replies View RelatedJSP :: Would Template Based Framework Generates A Lot Of Request Traffic?
Nov 29, 2014If I have a web page with a lot of data to show, say a lot of tables and graphics, would using non JSP based frameworks result in a lot more individual AJAX requests? For example if the page have 5 tables, with JSP the whole page will be returned to the browser with data for all 5 tables already. But if this is a pure HTML / Javascript based view, then we need to have each of the 5 tables to make individual AJAX requests in order to render the page. Is this indeed the down side for not using JSP?
The reason I'm asking is because I'm considering moving away from JSP to a template based framework such as Thymeleaf or Freemarker.
Difference Between Eclipse And JDK?
Feb 27, 2014I'm not sure if that's the right place to ask
But I am a bit confused:
I know that JDK means "Java Development Kit" , but isn't Eclipse the same thing? (so why it's called "IDE"?)
Or maybe Eclipse is a type of JDK?
Or actually JDK and Eclipse are 2 different things

View Replies View RelatedHow To Calculate Difference Between Two Dates
Oct 19, 2014I have been tasked with creating an invoice (school assignment). Part of the calculations is creating an interest depending on the amount of days between the current date entered, and invoice date entered (The program prompts the user to enter both the current and invoice dates by asking for the day, month and year).
We are also supposed to set the contructor to a default date of 1/1/1900.. but I don't know how or where to code that.
How to calculate the difference between the CurrentDate and Invoice. I have displayed the dates to the user as follows.
public void displayDate() {
System.out.println("
Today's Date: " + month + "/" + day + "/" + year);
}
public void displayInvDate() {
System.out.println("
Invoice Date: " + invMonth + "/" + invDay + "/" + invYear);
Difference Between LinkedList And ArrayList
Feb 19, 2014I have just begin to understand collections in Java. I read about the differences between LinkedList and ArrayList but have several doubts on it. I have mentioned them below
1) Why retrieving in ArrayList is faster then LinkedList?. Since both have the get method how does performance differ?.
2) How does re-sizing happens internally in ArrayList when a item is added or removed?. How slow this is compared to the pointer re-shuffling in LinkedList when a item is added or removed?.
Difference Between InputStream And InputStreamReader
Jul 11, 2014I read that InputStream is used for byte based reading it reads 1 byte at a time.And InputStreamReader is used for charcter based reading so it reads one charcter at a time so no need to convert this first to int then read it.Here is reading using InputStream.
input=new FileInputStream("D:/input.txt");
int c;
while((c=input.read())!=-1)
{
System.out.print((char)c);
}
and here is reading using InputStreamReader
input=new FileInputStream("D:/input.txt");
reader=new InputStreamReader(input,"UTF-8");
int c;
while((c=reader.read())!=-1)
{
System.out.print((char)c);
}
so what is difference between InputStream and InputStreamReader in both case i have to use a Int and then read it and at the end if I want to print that data I have to cast that with "(char)c".So what is advantage of using InputStreamReader?
